Mycena parca Aronsen

Gregarious among needles under Juniperus
communis or on open lawns. Autumn. M. parca has been found at three localities
in the South East of Norway. Robich (2003: 277-280) reported
it from Italy. Recently it has also been recorded from Denmark. See records in The
Norwegian Mycological Database.

Mycena parca is a member of the large
and complex section Fragilipedes (Fr.) Quél.
It is closely related to the widely distributed species Mycena leptocephala (Pers.: Fr.) Gillet, from which it can be distinguished
only by a close microscopic examination. The type is described
as a non-smelling, grey species. That was probably influenced
by dry weather. Later records have shown that it is a much
darker species, more or less with a nitrous odour. It can normally be
separated from M. leptocephala by the stipe, which
is conspicuously glabrous. The large, lageniform cheilocystidia should also be a good character.
